Background
The heat exchange station is a place where heat is concentrated and exchanged, in a heat supply system of the heat exchange station, a primary pipeline transfers heat of a heat source to a secondary pipeline through exchange, the secondary pipeline connects a user with the heat exchange station, and hot water circulates in the secondary pipeline through a circulating pump and transfers the heat to the user to supply heat for the user. As the secondary network system has long pipelines, complex pipeline structures and not tight pipelines, the water leakage phenomenon often occurs and the pressure fluctuation in the secondary pipelines is caused. In order to keep the pressure in the secondary pipeline constant or fluctuate within a certain range, a water replenishing system is required to be arranged, and manual water replenishing is mostly carried out manually according to the pressure of a return pipe of the secondary pipeline during water replenishing.
Meanwhile, some air is inevitably stored in the secondary pipeline circulating system, and the source of the air is secondary pipeline water supplement or pipe network leakage. Therefore, the secondary pipe circulation system inevitably mixes a part of the gas while replenishing water. This gas is mainly present in the secondary circuit in three forms:
first, gas accumulates in the form of gas slugs at high or local high points in the system, such as at the corners of pipelines, at the top of heat exchangers, and the like.
And secondly, the gas circularly moves along with the water in the secondary pipeline in a free bubble form.
Thirdly, the gas is dissolved in the water and circularly moves along with the water in the secondary pipeline.
In the existing form of the three gases, the first and the second are free gases, and the third is soluble gas, so that the three gases can be converted with each other continuously.
